I don't know about limiting the stack depth, although I think I recall some
discussion of it on the list a while ago.

Regardless of that, the alt-. interrupt should get you out of the infinite
recursion. On a Linux system with the a 3.6g1 Unix VM, I can run this:

  "Smalltalk installLowSpaceWatcher; createStackOverflow"

and I can break out of the recursion with alt-. as expected.

Which VM are you using when you have the problem?
